This is, I think, only a more copiously divided form of P. Willinckii 

 Moore^ not a distinct species. 



(6) P. ^¥ilclinkii, Moot-e.} Wigm. Jr., in Teysm., 1910, 156, 

 fig. 1-2. 



Basal fronds 2 or more, convex, entire, sinuate or the upper part 

 irregularly incised, afterwards brown. Fertile fronds mostly 4 — 7, 

 clustered, irregularly dichotomous with about 9 — 15 ultimate segments; 

 smallest fronds the least divided, cuneate at the base, rather nutant, 

 resembling those of P. bifurcatum G. Ghr.; largest fronds the most divided, 

 to about 60 — 90 cm. long, very narrowly cuneate (sublinear) below the 

 branching, pendulous or nearly so, agreeing nearly with the diagnosis of, 

 and resembling the table mentioned under, P. sumbawense Christ; under 

 surface tomentose with persistent, whitish, densely crowded, adpressed 

 pubescence of stellate hairs. — The description is taken from specimens 

 cultivated in the Buitenzorg Gardens, which do not agree exactly with 

 Wigman's figures.

Near P. coronarium Desv., but much smaller. Fertile fronds distinctly 

 stalked, stiffly erect, up to 30 cm. each way ; ultimate segments cuneate, 

 dilated towards the obliquely rotundate-truncate and more or less emarginate 

 apex; fertile segment longitudinally oblong, obovate or oval, 5 — 12 '/j cm. 

 long, to 8 cm. broad, subcucullate, the edge broadly recurved.
